Kilei zera'im for vegetables growing in separate containers sharing water
Question
I am growing peppers, tomatoes and cucumbers . Each vegetable is in a separate container on my porch that has a concrete floor. all of the pots are perforated. am I obligated to ensure a certain amount of distance between the containers due to laws of kilayim? For example, the pepper pot and tomato pot are sitting directly on the concrete floor and when I water them, and the water flows out of the bottom of the pots - the waters are mixing - maybe one is feeding from the other? Thank you

Rabbi Moshe Bloom
You need not distance the pots from one another, and it is perfectly permissible for them to receive nourishment from the same water. Lechatchilah, you can have both pots sit in a tray that collects the water.
The reason is that they are in separate pots, and this constitutes a heker. That is, it is obvious that the plants are growing separately.
Had you planted then in the same window box, however, you would need to distance them from one another.
